Match List-I with List-II regarding the components of a typical angiosperm embryo sac. List-I List-II A. Central cell I. 3 cells at chalazal pole B. Egg apparatus II. Possess filiform apparatus C. Antipodals III. 2 polar nuclei D. Synergids IV. 1 egg cell and 2 synergids Choose the correct answer from the options given below:
Options
- AA-III, B-IV, C-I, D-II
- BA-III, B-IV, C-II, D-I
- CA-IV, B-III, C-I, D-II
- DA-III, B-I, C-IV, D-II
Correct answer
A. A-III, B-IV, C-I, D-II
Step-by-step solution
The central cell is the largest cell of the embryo sac and contains two polar nuclei (A-III). The egg apparatus is located at the micropylar end and consists of two synergids and one egg cell (B-IV). The antipodals are three cells situated at the chalazal end (C-I). The synergids have special cellular thickenings at the micropylar tip called the filiform apparatus (D-II). Therefore, the correct matching is A-III, B-IV, C-I, D-II. Answer: A-III, B-IV, C-I, D-II
